Is this rivalry between the Labour Party's two most prominent black women or has there been an agreement? May be their relationship has improved since 1997 (from the Independent in 1997): "There is also, it is said, a "history" between her and the first black woman to be an MP, Diane Abbott, about whether or not Ms King tried to take Ms Abbott's seat in the neighbouring constituency, Hackney North. A Labour Party source described the relations between the two as "at best an armed neutrality".

There was some mention of Diane in Oona King's autobiography "House Music" but I can't remember if it was happy or not.
